Bitter Cukes

I’m growing cucumbers in my GH, a pickling variety (H-19) and an fresh eating variety (Telegraph Improved). Pickling ones are great, but the eating/salad variety ones seem to be uniformly very bitter, no matter how deeply they are peeled. I think my watering has been pretty uniform, and the plant itself is doing great.

Thought I would ask here before I yank the plant if there is anything else I could try to get rid of the bitterness.

Are you harvesting them when they are very young? If yes maybe you can add some shade clothe above the plants.

This is almost always a genetic issue. Toss the plant and get a variety that is rated for greenhouse growing as a slicer.


I have been harvesting them a bit on the big side, so I will try getting smaller ones.

Telegraph Improved is supposed to be a GH slicing variety. I’ve grown it before without this bitterness issue, so maybe it is just this particular plant. I had thought it might be a nutrient issue or something I could correct. That plant is growing extremely well.
